Not worth a post, because it's in french and it's my own work, but I wrote a while back an article on how to kill your NPC (non-player characters) in ways that matter, that relied a lot on examples from Whedon's works. In case that could be interesting to somebody here: http://www.sden.org/jeuderologie/trucs-de-mj/article/ne-tirez-pas-sur-la-chemise-rouge (the title means: "don't shoot the red shirt")

There's a fair few showrunners out there now who have claimed prior D&D experience, and I've always kinda figured that being a showrunner was not so very different from being a DM. Nice of WotC to notice. :P

All I thought of seeing this article was the scene in (I think) Chosen, where Andrew, Giles, Dawn, Xander and some Potentials are playing D&D.
"Giles: I used to be a highly respected Watcher, and now I'm a wounded dwarf with the mystical strength of a doily."

I guess my DMing could use a little Jossing up, but I'm afraid as geeky as my friends are for playing the game, they still haven't all watched much Whedon TV.
